We very excited about the episode today!

We are joined by A/Professor Jason Tye-Din - a leading expert in coeliac disease and immune-mediated gut disorders. He is Coeliac labratory head at the Walter and Eliza Hall Institute of Medical Research, a Mathison Centenary Fellow at the University of Melbourne, and consultant Gastroenterologist at the Royal Melbourne Hospital. His work focuses on the immunology of coeliac disease, novel diagnostic approaches, and developing non-dietary treatments. He is also one of the smartest (and nicest) clinicians that we have had the privilege  of working with. 

Joining Jason on the podcast today is Dr Cynthia Kanagasundaram. Cynthia is a UK trained Consultant Gastroenterologist with a vast experience in all things gastroenterology. She prides herself on innovation and has developed a novel GUT HUT service which slashed waiting times and improved patient care. She is embarking on a new stage of her career exploring novel diagnostics, techniques and treatments in Coeliac disease in the Tye-Din lab at the WEHI with A/Prof Jason Tye-Din as her supervisor.

Today we delve into the complexities of coeliac disease. We cover the diagnosis, dietary management, refractory celiac disease, models of care and future of coeliac.

The International Celiac Disease Symposium (ICDS 2026) will be held in Melbourne Australia 17-20 November 2026. Details at https://www.icds2026.org
